The aim of the Triton Initiative is to reduce the overall costs and increase the effectiveness of the environmental monitoring at MHK installations. This is achieved by: 1) supporting research and development to improve the technical performance of environmental monitoring devices (Funding Opportunity Awardee (FOA Support)2) improving the quality and relevance of the data collected by such devices (Fish Mesocosm Studies); and 3) standardizing monitoring technologies and data streams to improve comparability and between-project data transferability (Triton Field Trials – TFIT). This streamlines the evaluation processes required for MHK developments by targeting key environmental issues and establishing efficient ways to measure and monitor the environment and devices. Ultimately, these activities will accelerate the permitting process, which benefits regulators, developers and ocean users, and will reduce the cost of marine renewable energy.
